I've had similar problems while playing Black OPS 2.
I was under the impression that it affected i7's and AMD "8" core systems more. Windows 7 sometimes goes stupid and rapidly parks and unparks your cpu cores.
This might not be what you're experiencing, but googling a CPU unparking utility did the trick for me.
There might be other ways around this like, disabling any power saving features and stuff for your CPU/system. But I just ran the software instead to keep it simple :D
